Key Takeaway
Re-revision TKA management centers on four technical pillars—extensile exposure, impaction grafting, porous metal augmentation, and patella reconstruction—though no outcome data with specific numbers are reported in this symposium paper.

Summary
This AAHKS symposium paper addresses the surgical management of multiply revised TKA, focusing on extensile exposure techniques, impaction bone grafting, porous metal structural augmentation, and patellofemoral reconstruction. No primary outcome data are presented; the paper synthesizes expert technique guidance and algorithmic decision-making for re-revision scenarios complicated by bone loss and extensor mechanism insufficiency. Specific implant strategies and exposure algorithms are outlined without comparative efficacy data.
Key Limitation
The absence of any patient outcome data, complication rates, or implant survival figures renders the recommendations entirely expert opinion without quantitative support.
Original Abstract
The multiply revised total knee arthroplasty (TKA) poses unique surgical challenges. Patients who present to the office with a failed TKA or revision TKA expect durable, long-term fixation and improved function, yet bone loss and extensor mechanism insufficiency can easily complicate the reconstruction. The aim of this American Association of Hip and Knee Surgeons symposium is to provide up-to-date guidance for re-revision TKA with a specific focus on 1) safe exposure; 2) improved fixation with impaction grafting; 3) improved fixation using porous metal structural augmentation; and 4) managing the patella. After reviewing this paper, the reader should feel comfortable with standard and extensile exposures of a revision knee arthroplasty, understand the technique and outcomes for impaction bone grafting and the use of porous metal augmentation, and develop an algorithm for treating and optimizing patellofemoral kinematics through augmentation and reconstruction techniques.
